Subject: DWQ Project # 09-0204, Jackson County
Response to Request for More Information, 401 Water Quality Certification
Application for Pipe Extension, Little Savannah Road Widening, Western
Carolina University, West Campus Millennial Initiative Neighborhood 1
Dear Ms. Wiggs,
Mulkey, Inc. submitted a 404/401 Nationwide Permit (NWT) application package on
February 27, 2009 for a proposed extension to an existing pipe on Long Branch Creek in
Jackson County. The proposed pipe extension is a result of Little Savannah Road (SR 1321)
widening required by North Carolina Department of Transportation, as determined by a
Traffic Impact Analysis completed for the project. As noted in the 404/401 NWP
application package, the road widening and pipe extension are associated with the planned
construction of the School of Health and Gerontological Sciences building, which anchors
Neighborhood 1 of the Western Carolina University Millennial Initiative project.
Following your preliminary review of the NWP application, additional information was
requested in a letter dated April 16, 2009. The following information is provided for your
review, with each requested information item repeated from your letter followed by our
response. Where appropriate, supporting documentation is referenced and can be found
attached to this letter.
1. Please locate all wetlands, streams, and other waters of the State as overlays on the
site plan, or a note on the plans that states that none exist. Wetlands and streams
were indicated on Figure 2 of the aerial photo supplied. The plans did not clearly
indicate water features. Also, during a site visit by DWQ there appeared to be more
wetland areas within the project area than indicated on the aerial photo supplied.
Response: Attachment 1 provides full-size design plan sheets for the project. A new
design plan sheet is provided which shows the project site in relation to the verified
streams and wetlands (see Sheet C-100 in Attachment 1). Figure 2 depicting the project
study area boundaries and jurisdictional streams and wetlands delineated during field
investigations in 2007 was provided in the original 404/401 NWP application. Figure 2
has been revised to show the location of the project site in relationship to the verified
streams and wetlands (see Attachment 2).

All streams and wetlands within the study area boundaries (depicted in Figure 2) were
delineated during field investigations and were verified on November 13, 2007 during a
site meeting and field review with Loretta Beckwith, US Army Corps of Engineers, and
Kevin Barnett, DWQ Asheville Regulatory Field Office.
2. Please provide an 8 '/z x 11 inch copy of the NRCS County Soils map with the
project location shown.
Response: A new Figure 3 (see Attachment 3) depicts the project site in relationship to
the NRCS soil map units for Jackson County (GIS shapefile provided by NRCS Soils
DataMart). A Sediment and Erosion Control (SEC) calculations package (see
Attachment 4) is attached which contains a copy of the soils unit map page with the
project site shown in approximate location and soil unit descriptions from the NRCS
Jackson County soil survey.
3. Please provide a legend on the plans submitted, as certain symbols were not clearly
identified in the drawings.
Response: Please see construction documents for legends and symbol descriptions. The
National CADD standard for symbols was used on all construction documents. Any
sheet that differs from the National CADD standard has a legend depicting the symbols
used on that sheet.
4. Please indicate whether or not the proposed impacts have already been conducted.
During the DWQ site visit the large field at the southeast corner as indicated on
Figure 2 in the aerial photo has been filled and graded. DWQ representatives were
told this area would be used by the Fire Department as additional parking. Parking
would be considered an impervious and will need a stormwater control installed.
Response: Clearing or construction activities have not been conducted for the proposed
project. The portion of the property adjacent to the Fire Department is within the study
area boundaries shown on Figure 2. However, this area is not a part of the proposed
project. In a separate agreement unrelated to development of Neighborhood 1, Western
Carolina University has granted to the local fire department use of that portion of the
property adjacent to their facility (see Attachment 5).
Please provide cross section details showing the provisions for aquatic life passage.
The cross section typicals supplied were hard to read. A cross section of the culvert
to be installed is needed for review.
Response: Design plan sheets labeled as S-1 and S-1a depicting profile and cross section
views of the proposed pipe extension were provided in the original 404/401 NWP
application. Sheet S-1a (see Attachment 4) has been revised to indicate the pipe will be
buried 1 foot per requirements for fish passage. This revised design plan sheet also
depicts the pre-formed concrete junction box will be situated to create a six inch deep
area to allow shallow water pooling as requested by Mr. Dave McHenry, North Carolina
May 4, 2009
Page 3
Wildlife Resources Commission (NCWRC). Water pooling in the junction box will
provide a resting area for fish traveling upstream through the pipe.
Provide one BMP Supplement Form for each proposed BMP and Required Items
Checklist (htW://h2o.enr.state.nc.us/su/bmp forms.htm) alongwith all required
items. Some of the items listed on the required items checklist that were omitted
include:
a. A delineation of all drainage areas. It appears that the majority of the site will
drain to the sand filter trenches, with the exception of the north and east cut
slope drain, and a very small portion of the south roof drains will drain to the
bioretention pond.
Response: Drainage areas for each BMP feature are depicted on design plan sheets
labeled "Sand Filter Drainage Area Map" (see Attachment 6a) and "Bioretention
Drainage Area Map" (see Attachment 6b) and are included in the SEC calculation
package (Attachment 4)
b. On-site soil borings at the location of the proposed BMPs.
Response: A map depicting the location of all geotechnical soils borings, technical
analysis for each boring site, and descriptive portions of the geotechnical report are
provided in the calculations package (see Attachment 4).
c. A planting plan for the proposed bioretention cell.
Response: A new design plan sheet labeled C-215 (see Attachment 1) depicts the
planting plan, which includes a planting legend for the bioretention cell, is provided
in the SEC calculations package (Attachment 4).
d. Design calculation sheets for all proposed BMP(s) sized for both on-site and
off-site drainage. Supporting calculations must be signed, dated, and sealed.
Response: As a revision to the original submittal, we are providing six sand filter
supplemental forms for drainage areas 1 through 6 and one bioretention cell
supplemental form for drainage area 7. All supplemental forms have been included
with the required checklist for each BMP feature (see Attachment 4)
e. A notarized Operation & Maintenance Agreement for each BMP.
Response: Operation and Maintenance Agreement forms, signed and notarized by
Western Carolina University, are attached for each BMP structure (see Attachment 7).
7. The supplement forms provided, Plans D-1.06, and sheets Form SW401-Sand Filter
appear to conflict. Are the sand filter trenches open or closed designs? Most of the
stormwater appears to be piped to these trenches, but it is unclear if the trenches are
designed for piped stormwater or just overland flow stormwater.
May 4, 2009
Page 4
Response: The design is for the systems to be below grade in a vault system with grates
along the surface to allow sheet flow into the system. The confusion might be with the
use of the word "open" in the detail which does not mean the system is open to the air,
but that it does not contain sand in this area and is therefore "open" as shown in the
BMP manual figure 11-2a, page 11-5. This figure shows one sand filter chamber and
one "open" chamber with a weir to separate the two chambers. Drainage area maps are
provided in Attachments 6a and 6b as noted in our response above. The sand filters
receive both sheet flow and pipe flow. All drainage areas account for both onsite and
offsite along with sheet and pipe flow.
8. Please provide calculations to show that the outlet velocity will achieve a non-erosive
velocity of two feet per second or less for the peak flow from the 10-year storm.
The outlet structure for the sand filter trenches is receiving a large area of re-
concentrated flows.
Response: The complete stormwater calculations have been provided in the SEC
calculations package (Attachment 4) for your review. The outlet velocities are 2.76 cfs
and 6.97 cfs which are within the capabilities of the riprap dissipater to slow and
dissipate flow before entering 290 linear feet of undisturbed wooded area prior to
entering the stream.
9. A Finding of No Significant Impact (FONSI) will need to be received through the
State Clearing House prior to issuance of the 401 Certification.
Response: According to a letter from the State Clearing House, dated March 4, 2009, no
further review is required for this project (see Attachment 8). The FONSI was
submitted to the State Clearing House and available for review and comment through
April 2, 2009. A copy of the signed and dated FONSI signature page was provided in
the original 404/401 NWP application. One comment was received from the NCWRC
regarding the need to provide adequate fish passage. The pipe extension design has been
revised to address NCWRC concerns.
I hope the additional information provided herein is sufficient to allow final review of the
404/401 NWP application. If you have any questions or concerns regarding this project or
the attached information package, please contact Cindy Carr, Mulkey at [phone] or by
email to [e-mail].
Thank you.

Narrative
Western Carolina University (WCU) plans to construct WCU-School of Health &
Gerontology Sciences Building as its first building on the 344-acre WCU Millennial Initiative
on West Campus. The site is Nvid- in the township of Cullowhee in Jackson County. The
WCU-H&G building is approximately 145,000 square foot and will reside on a parcel under
the deed book 01470 and page 0283. The site would produce approximately 11 acres of
total disturbed area and approximately 6 acres of impervious. The project willinvolve
clearing, grading, and landscaping pertaining to the construction of school building, parking,
and other infrastructure.
The project area is located in the Chauga geologic belt of the Blue Ridge Mountain
physiographic province of North Carolina. The landscape in the project study area is
characterized by rolling hills with minor slopes along the drainageways. The project area is
shown on the Sylva South United States Geological Survey (USGS) 7.5-nvnute topographic
quadrangle map. Current elevations range from approximately 2,180 feet above mean sea
level (AISL) in the southeastern portion to 2,440 feet above AISL in the northwestern
portion.
The project is located in the Little Tennessee River Basin, subbasin 04-04-02. The 8-digit
USGS Hydrologic Unit Code for the study area is 06010203 (USGS, 1974). Long Branch
Creek is the only named stream within the study area; one unnamed tributary (UT) to Long
Branch Creek was also identified during the field investigation. The NCDWQ stream index
number for Long Branch Creek at this location is 2-79-31-6-(1) (NCDWQ, 2007). The
NCDWQ defines a perennial stream as a clearly defined channel that contains water for the
majority of the year (greater than 90 percent of the time). These channels usually have some
or all of die following characteristics: distinctive stream bed and bank, aquatic life, and
groundwater flow or discharge. An intermittent stream is defined as a clearly defined
channel that contains water for all but the driest months of the year. Both perennial and
intermittent streams are jurisdictional under state and federal regulations. During field
investigations, one perennial stream, Long Branch Creek, was delineated in the project area.
Erosion Control
The erosion control measures for the proposed education building will be designed,
constructed, and maintained to ensure compliance with the North Carolina Sedimentation
Pollution Control Act of 1973. The most sensitive area to protect on the site will be the
stream to the south and the delineated archeological areas. Tree Protection Fencing in
combination with silt fencing will be constructed around the archeological areas in order to
protect them during construction along with tree protection and silt fence on the toe of all
slopes to protect the stream. Temporary diversions may be constructed at the top and toe of
the proposed fill slopes to divert sediment-laden water from the construction site to
temporary sediment traps (for drainage areas less than five acres). The traps will be sized to
control the ten-year storm event. Check dams will be placed in the temporary diversions to
restrict the velocity of flow in these channels thereby minimizing erosion. Silt fence will be
installed between the diversion berms and adjacent areas to further ensure that silt does not
impact offsite properties and the stream located at the low point of the property. All inlets
into the proposed storm drainage system will be protected to prevent sediment from
entering the pipe system and being conveyed downstream. Construction entrances will be
installed at any entry points into the site to provide a buffer area where construction traffic
can drop their mud and sediment to avoid transporting this material onto private and public
roads, to control erosion from surface runoff, and to help control dust. The proposed
erosion control measures will be installed at the beginning of the construction, prior to any
land disturbance. All disturbed areas brought to final grade will be stabilized with permanent
vegetation within fifteen days. Once disturbed areas are stabilized and the site is approved
by the permitting agency, then the erosion control measures will be removed.
Site Utilities
Currently, an 8-inch waterline is located in Little Savannah Road (SR1321) along the entire
length of the property. The water service for the proposed building will be made from Little
Savannah Road in the location of the building's entrance. All required minimum design
separations between utilities will be maintained. Proposed fare hydrants will be located
within the property and located so that the building will have proper fire protection.
An existing 10-inch PVC sanitary sewer is located adjacent to the stream which extends the
length of the property parallel to Little Savannah Road. A portion of the existing sanitary
sewer is located between the proposed building and the existing stream. A manhole along
this section will be used to connect the proposed building so that the stream will not be
impacted any further. The wastewater from the proposed building will be collected and
transported to the existing sanitary sewer. The existing sanitary sewer is at elevation 2,178'
m.s.l. The proposed finish floor elevation for the building will be approximately 2,230' m.s.l.
Therefore, there should be no issues providing gravity sewer to the proposed building.
Stormwater drainage
Stormwater controls have be designed to maintain pre-development hydrographic conditions
for the 1-yr, 24-hr storm and will be maintained by the University. The design has
encompass a combination of sand filter and bioretention infiltration features as well as a
closed piping network facility. The conveyance system has been designed with a 10 year
design storm and the minimum piping size is 15 inches. The 1 inch storm was the design
standard that was required to meet DWQ standards for quantity control along with the
necessary treatment controls provided by the sand filters and bioretention pond. All uphill
storm runoff from the undisturbed areas have been designed to be captured by the concrete
ditch swale and routed around the site to be either released into the bioretention or into the
pipe system.
Roads and Parking
Three levels of approximately 213 parking spaces have been provided with the alternate to
add an additional 117 spaces in a forth level of parking. The parking has been designed to
allow access to three different levels of the proposed building. Handicap parking and
building access will be provided in both parking levels that serve levels 1, 2, & 3 of the
building. All parking and drive turns have a minimum 15' radius and all parking areas will
have a minimum 9'x 19' parking bay with a 24' drive aisle. A bus loop will be incorporated
into the lower levels of parking. An exclusive right in and left in turn lanes at the proposed
entrance are the only off-site road improvements and the extension of the existing 60"
culvert under the roadway section are anticipated for the development of the proposed
university building.

EvE-Evard-Cowee complex, 30 to 50 percent
slopes. This map unit occurs mainly as areas of a very
deep Evard soil and a moderately deep Cowee soil.
Both soils are well drained. The unit is on steep, south-
to west-facing ridgetops and side slopes in the low
mountains. Areas on ridgetops are long and narrow,
and areas on side slopes are irregular in shape. They
range from 10 to 75 acres in size. Typically, they are 50
to 60 percent Evard soil and 20 to 30 percent Cowee
soil. The two soils occur as areas too intricately mixed
and too small to be mapped separately.
The typical sequence, depth, and composition of the
layers in the Evard soil are as follows-
Surface layer:
0 to 6 inches, dark brown and strong brown gravelly
loam
Subsoil:
6 to 27 inches, red clay loam
27 to 35 inches, mottled red, yellowish red, and
strong brown loam
Underlying material:
35 to 60 inches, multicolored sandy loam saprolite
The typical sequence, depth, and composition of the
layers in the Cowee soil are as follows---
Surface layer:
0 to 5 inches, reddish brown gravelly sandy loam
Subsoil:
5 to 27 inches, red gravelly sandy loam and gravelly
sandy clay loam
Weathered bedrock:
27 to 60 inches, multicolored, weathered, high-
grade metamorphic bedrock
Permeability is moderate in both soils. The depth to
bedrock is more than 60 inches in the Evard soil. The
depth to weathered bedrock is 20 to 40 inches in the
Cowee soil. Surface runoff is slow in areas where
undisturbed forest litter is on the surface and rapid
where the litter has been removed.
Included in mapping are small areas of contrasting
Fannin and Saunook soils. Fannin soils have more mica
than the Evard and Cowee soils. Saunook soils are
along drainageways and have a dark surface layer.
Included soils make up about 15 percent of this map
unit.
Also included in mapping are soils that are similar to
the Evard and Cowee soils but have a browner subsoil
or have more rocks on the surface.
Much of the acreage in this map unit is used as
woodland. Other areas are used as pasture or hayland
or for specialty crops, recreational development, or
building site development.
This map unit is poorly suited to commercial timber.
It produces a lower volume of timber and has fewer
desirable species than highly productive soils, such as
Trimont soils. The slope, compaction, and the severe
hazard of erosion are management concerns. The most
common trees are scarlet oak, chestnut oak, black oak,
white oak, eastern white pine, pitch pine, Virginia pine,
hickory, yellow-poplar, northern red oak, and black
locust.
Hardwoods generally are preferred in stands that
have the potential for reforestation through sprouting
and where hardwood seedlings are available. In cutover
areas cutting all of the trees and large shrubs increases
the amount and quantity of the sprouts.
Old fields and other idle areas naturally reseed to
Virginia pine, pitch pine, eastern white pine, and black
locust. Genetically improved eastern white pine
commonly is planted in areas, such as old fields, where
the potential for reforestation is not good and seedlings
are not available. In cutover stands, preparing a site by
prescribed burning or applications of herbicide
increases the seedling survival rate and controls plant
competition. Preparing a site by prescribed burning also
minimizes the amount of debris and the hazard of
wildfires and lowers planting costs. Plant competition
should be controlled again a few years after planting.
Restricting the use of heavy equipment to dry periods
or to periods when the ground is frozen helps to prevent
soil compaction. When this map unit is wet, skid trails
and unsurfaced roads are soft and slick because of the
slope and the content of clay.
This map unit is poorly suited to pasture and is
unsuited to hay because of the slope, difficult access
across the steep terrain, and the severe hazard of
erosion. Erosion is a hazard in areas where plants are
becoming established and in sparsely vegetated or
overgrazed areas. Keeping the pasture in good
condition helps to control erosion and conserves water.
Operating farm equipment is dangerous on this map
unit.
This map unit is poorly suited to specialty crops. in
some areas, however, specialty crops are grown,
especially eastern white pine for use as Christmas
trees. The slope and the severe hazard of erosion are
management concerns. Operating farm equipment is
dangerous on this map unit. Specialty crops generally
are planted by hand. A few areas are used for growing
Norway spruce, mountain laurel, and rhododendron.
Establishing and maintaining sod in appropriate areas
minimize erosion, conserve water, and help to control
runoff. Vegetative filter strips can improve water quality
and provide wildlife habitat.
Jackson County, North Carolina
Sites should be designed so that runoff from the higher
adjacent areas and water from springs and seeps are
diverted from the roadbed. Establishing and maintaining
vegetation in bare areas helps to control erosion.
The capability subclass is lVe. Based on yellow-
poplar as the indicator species, the woodland ordination
symbol is 8A.
SaD-Saunook gravelly loam, 15 to 30 percent
slopes. This map unit consists mainly of moderately
steep, very deep, well drained Saunook and similar
soils on benches and on toe slopes in coves in the low
mountains. Individual areas are bowl shaped in the
lower part and are long and narrow further up the
drainageways. They range from 5 to 40 acres in size.
The typical sequence, depth, and composition of the
layers in the Saunook soil are as follows-
Surface layer:
0 to 9 inches, dark brown gravelly loam
Subsoil:
9 to 24 inches, strong brown gravelly clay loam and
gravelly sandy clay loam
24 to 44 inches, strong brown gravelly sandy loam
and sandy loam
Underlying material:
44 to 60 inches, yellowish brown cobbly fine sandy
loam
Permeability is moderate. The depth to bedrock is
more than 60 inches. Surface runoff is slow in areas
where undisturbed forest litter is on the surface and is
medium or rapid where the litter has been removed.
Runoff from the higher adjacent areas is concentrated
in the concave areas. The seasonal high water table is
more than 6 feet below the surface.
Included in mapping are small areas of Whiteside,
lvard, and Cowee soils. Evard and Cowee soils are on
the adjacent uplands. Also, Cowee soils are moderately
deep to weathered bedrock. Whiteside soils are
moderately well drained and are in depressions.
Included soils make up about 15 percent of this map
unit,
. Also included in mapping are soils that are similar to
the Saunook soil but have a redder subsoil and some
areas of soils that are near the area of contact with the
uplands and have 3 to 10 inches of recent overwash.
Much of the acreage in this map unit is used as
pasture or hayland. Some areas are used as woodland
or for specialty crops, recreational development, or
building site development.
This map unit is moderately suited to pasture and
hayland. The slope, soil compaction, a severe hazard of
ofosion, and damage to streambanks are the main
109
management concerns. Grazing during wet periods
causes compaction, reduces the rate of water
infiltration, and increases the runoff rate. Erosion is a
hazard in areas where plants are becoming established
and in sparsely vegetated or overgrazed areas.
Properly locating watering facilities and stream
crossings can help to control damage to streambanks.
Operating farm equipment is difficult on this map unit.
This map unit is moderately suited to commercial
timber. The slope is the main limitation. Yellow-poplar is
the most common tree. Other trees include black
cherry, American beech, sweet birch, northern red oak,
eastern white pine, white oak, scarlet oak, eastern
hemlock, red maple, and yellow buckeye. Black walnut
is also well suited to this soil. This soil is seldom
managed for timber because of the small size of the
mapped areas and the potentially higher profits from
crops, building sites, pasture, or hayland.
Reforestation of hardwoods occurs dominantly
through sprouting. Cutting all of the trees and large
shrubs increases the number and quality of the sprouts.
When stands are thinned, black cherry, northern red
oak, and sugar maple generally are left standing.
Old fields and other idle areas naturally reseed to
yellow-poplar, Virginia pine, pitch pine, eastern white
pine, and black locust. Genetically improved eastern
white pine commonly is planted in areas, such as old
fields, where the potential for reforestation through
sprouting is not good and hardwood seedlings are not
available. In cutover stands, preparing a site by
prescribed burning or applications of herbicide
increases the seedling survival rate and controls plant
competition. Preparing a site by prescribed burning also
minimizes the amount of debris and the hazard of
wildfires and lowers planting costs. Plant competition
should be controlled again a few years after planting.
Restricting the use of heavy equipment to dry periods
or to periods when the ground is frozen helps to prevent
soil compaction. Skid trails and unsurfaced roads are
very slick and highly erodible during wet periods
because of the slope, the content of clay in the subsoil,
and the content of organic matter in the surface layer.
This map unit is moderately suited to specialty crops,
such as landscaping plants, Christmas trees, and
ginseng. The slope, the severe hazard of erosion, and
runoff from the higher adjacent areas are the main
management concerns. The most common landscaping
plants are eastern hemlock, Norway spruce, mountain
laurel, dogwood, white birch, Bradford pear, and
rhododendron. Fraser fir and eastern white pine are
grown for use as Christmas trees.
This map unit is moderately suited to plants that are
to be balled and burlapped during harvesting.

Report of Geotechnical Exploration

(Updated February 12, 2008)
2.0 SITE GEOLOGY
a
The project site is located in the Blue Ridge Physiographic Province. The bedrock in this province
is a complex mixture of igneous, sedimentary and metamorphic rock that has been repeatedly
squeezed, fractured, faulted and distorted by past tectonic movements. The virgin soils encountered
in this area are the residual product of in-place weathering of rock, which was similar to the rock
presently underlying the site. In areas not altered by erosion or disturbed by the activities of
development, the typical residual soil profile consists of clayey soils near the surface, where soil
weathering is more advanced, underlain by sandy silts and silty sands. The less weathered soils
exhibit relict features of the parent rock, including foliation patterns and joints. It is not uncommon
to find colluvial soil (soil deposited by previous landslide activity) at the base of steep slopes.
The boundary between soil and rock is not sharply defined. This transitional zone termed "partially
weathered rock" (MR) is normally found overlying the parent bedrock. Partially weathered rock is
defined, for engineering purposes, as residual material with standard penetration resistance values in
excess of 100 blows per foot. Fractures, joints, and the presence of less resistant rock types facilitate
weathering. Consequently, the profile of the partially weathered rock and hard rock is quite irregular
and erratic, even over short horizontal distances. Also, it is not unusual to find lenses and boulders of
hard rock and zones of partially weathered rock within the soil mantle, well above the general
bedrock level.

Nineteen soil test borings were drilled at the approximate locations shown on the attached Boring
Location Plan (Figure 2). The boring locations were marked at the site by a surveyor under contract
to you. The boring elevations shown on the attached Test Boring Records were estimated using the
provided topographic map and should be considered approximate.
Borings B-1 through B-15 were drilled in the area of the proposed building. Borings B-16 through
B-19 were drilled in the area of the proposed parking lots. At your request, we did not drill two
borinL,s located near the southwest corner of the construction limits because they were located in/near
an area of archeological significance.

Jarzuarv 30, 2008
MACT C Project No.: 6685071718.01 (Updated February 12, 2008)
The soil test borings were drilled by mechanically twisting hollow-stem augers into the soil and
extended to the assigned termination depths of 20 to 60 feet or auger refusal, whichever occurred
first. Soil sampling and penetration testing were performed in general accordance with ASTM D
1586. At assigned intervals, soil samples were obtained with a standard 1.4-inch I.D., 2-inch O.D.
split-spoon sampler. The sampler was first seated 6 inches to penetrate any loose cuttings, and then
driven an. additional 12 inches with blows of a 140-pound hammer falling 30 inches. The number of
hammer blows required to drive the sampler the final 12 inches was recorded and is designated the
'N Value" or "penetration resistance". The N-Value, when properly evaluated, is an index to soil
strength and foundation supporting capability.
Representative portions of split spoon samples were sealed in glass jars and returned to our
laboratory where they were visually classified by a geotechnical engineer. Depth to ground water,
where encountered, was measured in the boreholes at the time of drilling and after a period of at least
24 hours, as noted on the boring records. The boreholes were filled with drill cuttings after the
depths to ground water measurements were taken.
Three undisturbed samples were obtained from Borings B_4, B-5, and B-14. Two bulk soil samples
were obtained in cut areas of the site (borings B-4 and B-8) to represent the types of soil expected to
be used as fill in the pafking lots. The undisturbed and bulk samples were transported to MACTEC's
Charlotte, North Carolina laboratory for testing.
Upon completion of drilling, MACTEC performed a Refraction Microtremor (ReMi) Survey to
measure the shear-wave velocity of the soil within 100 feet below the subgrade elevation of the
proposed building in order to determine the seismic site classification based on the North Carolina
State Building Code. The results of the ReMi survey are briefly discussed in Section 6.0 and the
Report of Seismic Shear Wave Measurements dated January 22, 2008 is included in Appendix A of
this report.

(Updated February 12, 2008)
4.0 LABORATORY TESTING
Laboratory testing is currently being performed on bulk and undisturbed soils samples collected
during drilling. Triaxial shear and classification testing (sieve analysis, atterberg limits) are being
performed on the undisturbed samples to determine soil shear strength parameters for use by the soil-
mail wall designer. Laboratory tests being performed on the bulk samples include classification tests,
standard Proctor testing, and California Bearing Ratio testing (for use in pavement design). The
laboratory test results will be provided in an addendum to this report.
5.0 SUBSURFACE CONDITIONS
The nineteen soil test borings were drilled at the approximate locations shown on the attached Boring
Location Plan. A series of small dozer roads were installed to access each of the surveyed boring
locations. Construction of the dozer roads for drilling access resulted in disturbing the soil at the
original ground surface; therefore, only minor amounts of topsoil and organic material was
encountered and noted on the attached Test Boring Records. Based on observations during and after
construction of the dozer roads, we estimate that between 3 and S inches of topsoil exists at the
ground surface. Topsoil can be expected to be encountered at varying thicknesses across the site.
The following descriptions provide a general summary of the subsurface conditions encountered.
The attached Test Boring Records and Subsurface Profiles represent our interpretation of the field
drilling logs based on engineering examination of the field samples. The lines designating the
interfaces between various strata represent approximate boundaries and the transition between strata
9 - may be gradual. It should be noted that subsurface conditions will vary between the boring locations.
5.1 Soil Conditions
Residual soil was sampled from the ground surface to termination depths in each of the soil test
borings. In general, the residual soil consisted of loose to firm silty sand (with average N-values of 7
to 15 bpf) and firm to stiff sandy silt (with average N-values of 5 to 12 bpf). The residual soil did not
significantly increase in density or consistency with depth within the explored depths. Dense soil
(average N-value greater than 30 bpf) was encountered in boring B-5 between depths of 30 and 40

feet and in boring B-8 between 40 and 45 feet depth. Partially weathered rock was encountered in
boring B-8 from 44-feet depth to boring termination at 45 feet. Auger refusal was encountered in
boring B-5 at a depth of 40 feet.
5.2 Ground-Water Conditions
At the time of drilling and after a period of at least 24 hours, the boreholes were sounded for the
presence ground water. Where encountered, the depth to ground water was recorded and is shown on
the attached Test Boring Records. Ground water was encountered at the approximate depths and
elevations shown in the following table. The measured depths to ground water are expected to be
greater than typical for the site due to the extended period of drought that has occurred in the site area
over the past several years.

Re: Amendment to Archaeological Resources Protection Act Permit 982
Data Recovery Excavations at Locus 2, 31JK477, Millennium Initiative Campus
Western Carolina University, Jackson County
Dear Mr.. Garrow
We have received your proposal and research design for data excavations at Locus 2 of site
31JK477, located in the Millennium Initiative Campus at Western Carolina University and your
request for an amendment to the existing permit. These additional investigations include.
excavation of an 8-meter by 8-meter block, feature excavation and analysis, coilection'and
analysis of flotation, carbon., floral and faunal samples, as well as appropriate mapping and
photography. The purpose of these excavations is to mitigate the adverse effects to the site as a
result of proposed construction.
The area involved in the excavations remains unchanged. The schedule for the existing permit
duration will need to be changed, as well as the reporting schedules. It is our understanding that
Western Carolina University is anxious to have the excavations conducted as soon as possible so
development of the Millennium Campus project may proceed.
Given these circumstances, we concur that an amendment to the existing Archaeological
Resources Protection Act Permit #82 is appropriate. Additional field investigations can begin on
Monday, November 17, 2008. The preliminary field report should be submitted on or before
February 2, 2009. The draft report should be submitted on or before July 31, 2009. and the final
report on or before October 30, 2009. We do request that you submit four hard copies and one
electronic. copy' of.the reports to the. Office of State Archaeology rather. than the two copies
included in your proposal.
Please append this letter and your proposal to your original permit for future reference. By copy
of this letter, we are notifying Galen May, Western Carolina University Architect and Wanda King

Management Summary
Western Carolina University Millennial Campus Neighborhood #1
Cullowhee, Jackson County, North Carolina
Phase Ili Data Recovery
31 JK477, Locus I
Prepared by LaDonna Rogers Stroupe, RPA
March 18, 2009
Archaeologists with MACTEC Engineering and Consulting, Inc. (MACTEC) conducted
Phase III Data Recovery excavations in the late autumn and winter of 2008-2009
(November 17 2008 to January 9, 2009 and February 23 to March 6, 2009) on land
proposed for the development of Western Carolina University's Millennial Campus
Neighborhood #1, Health and Gerontological Center in Cullowhee, Jackson County,
North Carolina. The project area is located in the central part of Jackson County, west of
WCU's main campus and is bounded by Little Savannah Road (Highway 1367) to the
south, a power line right-of-way to the north, the Cullowhee Fire Department to the east
and Gribble Gap Road to the west. Phase 11 Testing carried out by MACTEC
archaeologists during July of 2008 revealed intact cultural deposits within Site 31JK465
and Locus 1 and Locus 2 of Site 31JK477. Therefore, mitigation of these sites was
required prior to construction. A scope of work was produced that included the
development of preservation plans for Site 31JK465 and Locus 2 of Site 31JK477, and an
archaeological Data Recovery Plan was developed for Locus 1 of Site 31JK477.
The Data Recovery excavation for Locus 1, Site 31JK477, was completed between
November 17, 2008 and January 9, 2009, and between February 23 and March 6, 2009.
A total of 64 units arranged in an eight-meter by nine-meter block were excavated by
hand and the soil was dry screened through '/a-inch hardware cloth. A one-meter baulk
remained in place in the center of the excavation block. The eastern side of the block was
excavated to one meter below surface, which revealed sterile subsoil (Figure 1). Upon
excavating the western side of the block to one meter below surface, subsoil was not
reached. Therefore, the excavation was stepped in and an area measuring two meters by
six meters was excavated to sterile subsoil (Figure 2).
A total of 54 features were recorded within the excavation area. This total includes 21
features that were found to be non-cultural disturbances, such as trees or rodent burrows.
The remaining 33 features consisted of rock clusters, postholes, stains, pits and burnt
earth features. The majority of the cultural features were identified in the southeastern
part of the block, and it was found that some rock features continued through the baulk to
the southwestern part of the block. The majority of the recorded features can be dated to
the Late Archaic period, However, for a few features, the date was indeterminate due to
the lack of diagnostic material within or around those features.
Rock clusters ranged in size from 55 centimeters by 32 centimeters to 3.70 meters by
1.80 meters, and were typically amorphous. The thickness of these features ranged from
Management Summary - Phase III Data Recovery March 18, 2009
Western Carolina University Millennial Campus Neighborhood #1
10 centimeters to 30 centimeters, and very few artifacts were recovered from rock
features. Postholes were approximately 10 centimeters in diameter and approximately 10
centimeters deep. Soil from posthole features was collected for floatation. The plan view
of the dark stains that were recorded varied from amorphous to square or oval-shaped.
The largest of these measured 2.0 meters by 0.75 meters and was 42 centimeters thick,
and the smallest measured 32 centimeters by 24 centimeters and was 30 centimeters
thick. Artifacts recovered from stains were typically comparable to the artifacts
recovered from the surrounding matrix. Two larger circular features, possibly pits, were
recorded and the first measured 47 centimeters by 37 centimeters (Feature 20) and the
second measured 30 centimeters by 27 centimeters (Feature 26). The soil from these
features was collected and retained for floatation, but upon floatation it was found that
Qualla ceramics were recovered from Feature 26. One burnt earth feature (Feature 39),
which was possibly a hearth, was recorded. This feature measured 1.0 meter by 0.50
meters and approximately 18 centimeters thick. No cultural material was recovered from
this feature, but a Late Archaic stemmed projectile point was recovered from the
surrounding matrix. Therefore, it is likely that Feature 39 is of Late Archaic date.
Analysis of the artifacts and floatation samples that were recovered from Locus 1, Site
31 TK477 is ongoing but nearing completion. The majority of the artifacts are lithic
materials that relate to the Late Archaic occupation and midden on the site. However,
prehistoric ceramic artifacts were recovered that relate to the Qualla midden that was
recorded.
The Late Archaic midden has produced extensive evidence for stone tool making. A very
large sample of Late Archaic projectile points or knives has been recovered. Among
these are diagnostic projectile points that were fashioned from stone that was brought
from other locations to the site, most notably rhyolite and quartz. These tools will be
studied in order to better understand the nature of the toolkits that were being replenished
on the site. Additionally, it is evident that that quartzite cobbles were recovered from
Long Branch Creek and utilized for stone tool making. A replication study has been
carried out on local quartzite in order to determine the types of shatter and debitage this
material would produce so the material that was recovered during excavation might be
better understood.
Analysis of the stratigraphic sequence of this site is ongoing and is crucial to the
interpretation of the cultural deposits. However, preliminary interpretations of the site
suggest that a Qualla midden was sealed by a colluvial episode and that, beneath the
Qualla midden, a Late Archaic midden and living surface were scaled by another
colluvial episode. This Late Archaic deposit, measuring up to 80 centimeters thick at its
thickest point, also includes what appears to be a Late Archaic house. Evidence for the
house includes posthole features and a potential portion of the house that was retained in
profile along the eastern extent of the excavation block.

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
- Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
- Heavy equipment will NEVER be driven over the bioretention cell.
- Special care will be taken to prevent sediment from entering the bioretention cell.
- Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.

SCH File # 09-E-6075-0187
Dear Mr. McHenry:
Thank you for your February 2, 2009 comments on the subject project. In response to those comments
regarding the culvert extension and stormwater management, we are providing the following information.
The proposed culvert extension is a result of the road widening required by NCDOT, as determined by the
Traffic Impact Analysis completed for the project The widening will extend the pavement beyond the
current end of pipe. The entrance drive to the site was placed in the proposed location to minimize
impacts to the stream and the archaeological areas of interest Placement to the east or west would cause
further disturbance to either resource. The proposed culvert extension will be buried one foot to allow
passage of aquatic life, and all stream impacts are currently being reviewed in the Section 404/401 permit
process.
Stormwater control will be addressed in several different ways. The building roof drains will be routed to a
bioretention area to the south of the building near the maintenance path that connects to the building. The
building will also have a roof garden that will not only act as a public feature, but will also reduce runoff,
Rip rap dissipater pads and long undisturbed flow paths leading to the stream will be utilized to allow for
natural cleaning and dissipating effects of undisturbed natural areas.
Please feel free to contact me at [phone] or cfreeman(@mulkevinc.com if you need additional
information or have any other questions.

Office of Legislative and Intergovernmental Affair
FROM: Dave McHenry, Mountain Region Coordinator
Habitat ConwTvation Program
DATE: February 2, 2009
SUBJECT: ]Ernvira[uuentat Assessment for Western Carolina Uttivocsity West Campus Millennial
Iuitiative, Neighborhood No. 1, Jackson County
GLLk No. 09-0787
Biologists with the North Carolina Wildlife Resources Commission (Commission) reviewed the
)Environmental Assessment (EA) for the project. COti73rteDts from the Commission are provided under
provisions of the Fish and Wildlife Coordination Act (48 Stat. 441, as amended; 16 U,S.C• 661 et seq),
the North Carolina Statutes (G.S.113-131 et seq.), and the National Environmental ]Policy Act (42 U.S.C.
4332(2)(c)).
The project involves developing the Western Carolina University West Campus Millennial Initiative,
Neighboxhood No. 1 on a 40 acre tract along Long Branch. The site is situated in the Tuckaseegee River
watershed which, supports sonsitive aquatic life like The Appalachian elktoe mussel (federally-listed
Endangered), L*ng Branch supports wild rainbow trout.
There is insufficient infbmWion in the EA. to Fully evaluate the prr jact's effects on fish and wildlife
resources. The Commission requests that the following be addressed:
1 • Alternatives to the culvert extension in Long Branch should be evaluated bwAwe this stream
supports wild trout. Culvert extensions can impede or block fish movements, paAicularly if tmy
result in a hanging outlet condition. If relocating the enttance road to the west to avoid the stream
is not possible, then the extended culvert needs to be partially rmcssed into the stream bed to
reduce the likelihood of a barrier,
2. There will be a considor*le amount of impervious m-ea crested, but there are no details tit the EA,
